hi, as far as i know this is not sleep paralasis as you have to time it right to get sleep paralasis because of your rem cycle, you probably enterd your n/rem (non rem) which allows your body to toss and turn while you arn't dreaming and cut off the blood supply shortly before you woke.

Yeah, like "Pins and Needles" thats what we call it here. I've woken up with half of my torso and arm all frozen before. It's a blood circulation thing.

I am an Engineering student, and have yet to experience a lucid dream. Currently on break, I am hoping to try and master the technique as it will give me some peace during the busy school year. Any advice or links are appreciated. Feel free to pm me.
